LAMP-BRACKET.

SPECIFICATION forming part of Letters Patent No. 297,317, datedApril 22,1884.

Application filed November 30, 1883. (No motleli) .TO M! whom it nattyconcern:

Be it known that I, ALFRED THURBER, of.

Concord, county of Contra Costa, and State of California, have inventedan Improvement in Lamp-Brackets; and I hereby declare the following tobe a full, clear, and exact description thereof.

My invention relates to a bracket or support for lamps; and it consistsof an arm pivoted or suspended and having an automatic clamp at itsouter end, the jaws of which are so constructed as to open and admit theshank or top of the lamp when it is presented, and close to hold itssuspended, as will be more fully explained by reference to theaccompanying drawings, in which Figure l is a perspective view of mylampbracket. Fig. 2 is a view with the plate L lett oft. Fig. 3 is aview looking underneath the bracket. Fig. 4 is a modification.

A is an arm, which may be of any ornamental design or contour. Its innerend has a pin, B, which fits into a socket, C, to allow the bracket toswing from side to side. The outer end is flattened and spreads outhorizontally, forming two arms, D, upon which the jaws or clamps E aresupported, and they are pivoted at F F, so as to open or close. Theouter ends of the jaws have an opening, G, formed between them, of asize to receive and hold a lamp-shank. This opening, which is formed bythe semicircular shape of each arm, does not quite close at thefront,and the outer ends of the arms curve outward and away from eachother to form an inclined or flaring opening at H, so that when theshank or top of the lamp is passed into it the arms separate and allowit to enter the central opening. At the rear ends the arms separate inan arched form, as shown at I, and asemicircular curved spring, M, isfitted into the space thus formed between the arms, its ends acting toseparate the rear ends and close the front. In

order to keep this spring in place, a projection,

J, is formed upon theinner end of each ofthe arms, and the ends of thespring rest against, them. The portion of the bracket upon which themovable armsare pivoted is made thinner than the main part, andprojections K are formed upon each side of the rear ends of the arms atI, to prevent their being separated too far by the action of the spring.A plate, L, has its rear end beveled to fit into a corresponding recesson the bracket, and its front has arms D, corresponding with the arms Dupon the bracket. These arms project above the jaws E, and the platebeing secured by a screw or otherwise, the jaws and spring are inclosedbetween them, making a neat finish and protecting the working parts.

It will be manifest that a hand or other lamp without a shank might alsobe held in a similar manner by supporting it upon ashelf in such aposition below the clamp that the latter would encircle the neck or topof the lamp. The clamp may have an arm from an upright, with aset-screw, by which it can be adjusted for height.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a lam p-bracket having the elevated sides K, arms D, the pivoted jawsE, forming a circular central opening adapted to receive the shank of alamp, and provided with a flaring or 'beveled mouth, in combination withthe backwardlyextending arms or lugs J, connected by a curved spring,whereby the jaws are closed automatically, all substantially as shown,and for the purposes described.

In witness whereof I have hereunto set my hand.

ALFRED THURBER.
